3D plots with data.frame

Dear all,

    Thank you for any help. I have a data.frame and would like to plot
it in 3D. I have tried wireframe() and cloud(), I got

scatterplot3d(xs)
Error: could not find function "scatterplot3d"

wireframe(xs)

Error in wireframe(xs) : no applicable method for "wireframe"

persp(x=x, y=y, z=xs)

Error in persp.default(x = x, y = y, z = xs) :
        (list) object cannot be coerced to 'double'

class(xs)

[1] "data.frame"
Where x and y were a sequence of my min -> max by 50 of xs[,1] and xs[,2].

my data is/looks like:

dim(xs)

[1] 400   4

xs[1:5,]

        x       y     Z1     Z2
1 27172.4 19062.4      0    128
2 27000.9 19077.8      0      0
3 27016.8 19077.5      0      0
4 27029.5 19077.3      0      0
5 27045.4 19077.0      0      0

    Cheers,

    Paul

You could try the function 'plot3d', in package 'rgl':

library(rgl)
?plot3d
x<-data.frame(a=rnorm(100),b=rnorm(100),c=rnorm(100))
plot3d(x$a,x$b,x$c)
